    Notes: That the palliatae of Plautus and Terence, besides purporting to depict Greek life, were in general adaptations of Greek plays has always been known. Statements in the prologues of the Latin plays and by other ancient authors left no room for doubt about this, while allowing the possibility of some exceptions. The question of the relationship of the Latin plays to their Greek models was first seriously addressed in the nineteenth century, mainly by German scholars, under the stimulus of Romantic criticism which attached paramount importance to originality in art. Since then the question has been constantly debated, often with acrimony, and to this day very different answers to it continue to be given. Yet the question is obviously important, both for those who would measure the artistic achievement of the Latin dramatists and for those who would use the plays to document aspects of Greek or Roman life. It is not disputed that Plautus' plays contain many Roman allusions and Latin puns which cannot have been derived from any Greek model and must be attributed to the Roman adapter. What is disputed is whether this overt Romanization is merely a superficial veneer overlaid on fundamentally Greek structures or whether Plautus made more radical changes to the structure as well as the spirit of his models.

    Notes: The pattern of basement membrane deposition was investigated in benign and malignant choroid plexus tumours using an immunocytochemical method to detect laminin, an intrinsic basement membrane component. The results were compared with intracranial ependymomas and myxopapillary ependymomas of the filum terminale. Expression of the intermediate filaments cytokeratin and glial fibrillar acidic protein (GFAP) and the epithelial marker carcino-embroyonic antigen (CEA) was also assessed. Laminin was detected in a subepithelial location in all the choroid plexus tumours but in none of the ependymomas, although basement membrane fragmentation was seen in the choroid plexus carcinomas. In contrast. GFAP was present in all the types of tumour examined. Cytokeratin (as detected by CAM 5.2) was present in all the choroid plexus lesions and also in the ependymomas arising in the spinal canal. CEA was not detected. We conclude that immunostaining for laminin assists distinction between choroid plexus tumors and papillary ependymomas and between benign and malignant choroid plexus tumours.

    Notes: The effects of transfusing cores of grass silage with mixtures of oxygen and nitrogen containing 0%, 0·2%, 2%, 5% and 20% oxygen were investigated. Changes in populations of yeasts, lactobacilli and streptococci were measured and the relationship between populations after 7 days' transfusion and oxygen concentration were tested against the predictions of two models, based on Monod and logistic growth functions. Yeasts were related to oxygen by the Monod model, while lactobacilli and streptococci were related by the logistic model. The differences were ascribed to yeasts initiating deterioration by growing aerobically, while lactobacilli and streptococci grew fermentatively once the environment had changed following yeast growth. Dry-matter losses were related to oxygen by the Monod model. Changes in temperature were related to dry matter loss (through measurements of CO2 evolution) using a simple heat balance model.

    Notes: Protein and N—linked glycoprotein biosynthesis was studied in histologically verified normal epidermis, actinic keratoses, keratoacanthoma, intra-epidermal carcinoma and squamous-cell carcinoma using polyacrylamide gel electrophoresis (PAGE). The PAGE profiles of 3[H]—leucine-labelled proteins and 3[H]-mannose-labelled glycoprotein from all disease states studied differed from each other and from normal epidermis. A large 3[H]-mannose-labelled glycoprotein region (band A) with a peak at 97–92 kDa appeared to indicate the presence of a relatively large proportion of basaloid cells in the tissue. An associated peak in the region of 78–74 kDa also appeared in normal epidermis and what appeared to be non-invasive lesions. The main region of change in all lesions corresponded to the 66–34-kDa region (bands B and C). The absence of a group of glycoproteins and proteins in the 62-58-kDa region appeared to be specific for invasive squamous-cell carcinoma. All tumours showed a peak at 38–34 kDa which was not present in normal epidermis. Actinic keratosis had a pattern similar to normal epidermis except that the peaks of band B tended towards the higher-molecular-weight end of the band than those in normal epidermis and peaks at 28–22 kDa were seen. The latter seemed to correspond to the presence of a high proportion of spinous cells in the tissue sample.

    Notes: [Auszug] SEVERAL textbooks on Quaternary geology or environmental history have appeared in recent years, and the authors of each have faced the same dilemma: how to get across the breadth and scope of this vast (and still growing) subject within the confines of a standard text. The answer, of course, is to ...

    Notes: Abstract A series of 6 infants subjected to child abuse is presented in whom contusional tears of subcortical white matter were detected during life by intracranial sonography. The sonographic appearances of this highly pathognomonic marker of shaking injury are described for the first time and their significance discussed. On the basis of our experience we suggest that high resolution cranial sonography is an extremely valuable part of the diagnostic work up in cases of suspected non-accidental injury.

    Notes: Abstract The reaction π+ p→π+π+ n was studied in the vicinity of the reaction threshold at ten incident pion beam momenta from 297 MeV/c to 480 MeV/c. From data angular distributions, invariant mass spectra and integrated cross-sections were deduced. The chiral symmetry breaking parameter as determined by this reaction equals to ξ=1.56±0.26±0.39, where the first error is experimental, while the latter reflects the uncertainty in the ansatz used in the extrapolation to the reaction threshold. A comparison with the other reaction channels of the reaction πp→ππN indicates that a single parameter (ξ) is not sufficient to describe low energy ππ interactions.

    Notes: Abstract We report on results of an experiment to study the reaction π− p → π− π+ in the incident pion momentum region between 295 and 450 MeV/c. A departure from phase space was observed in invariant-mass spectra and angular distributions which cannot be explained with Δ and ϱ resonance production. It indicates aI=0,J P = 0+ π− π+ final-state interaction.
